Components of IoT10 Contextual reasoning – How to improve application capacity to sense, understand, and reason about complex and dynamic data and situation? Knowledge representations and interaction techniques – How to augment cognitive reasoning with perceptual reasoning through visual representations and interactions? Data Representations and transformations – How to transform data into a representation that is appropriate to the reasoning task and effectively patch the important content? Production, presentation, and dissemination – How to convey analytical results in meaningful ways to various audiences?
